ICE BOAT.

Application filed January 24, 1927. Serial No 162 97 3.

This invention relates to ice-boats and it has to do particularly with an ice-boat which will float and propel. itself in water.

Among the objects of the invention is the provision of a boat which is propelled by an air propeller, and which is provided with supporting members which constitute ice runners and pontoon iike members so that the boat will travel over ice or through water without involvin an change in its structure. A steering or guiding mechanism of novel arrangement is included and this steering mechanism functions for guiding the boat on ice or in water. The steering mechanism has an automatic action so that if the boat should leave the ice and enter water the steering de vice changes its positionso that guiding members thereof act in the manner of a rudder. I

In the accompanying drawings:

Fig. 1 is a side elevation of a boat constructed in accordance with the invention.

Fig. 2 isa front View of the boat.

Fig. 3 is a rear View showing the guiding mechanism. 1

Fig. 4: is an enlarged detail showing the steering mechanism'looking in the direction of the arrow of Fig. 1.

The boat-includes a body, which may be designed for holding several passengers. A

motor, preferably of the internal combustion type is mounted within the body for rotating the propeller 2. The body is supported by a pair of spaced pontoon-like members 3. These members may be of any desired cross section, and are made of hollow material with sufficient buoyancy to support the boat in water.

The pontoons preferably are longer than the body and extend forwardly thereof and each pontoon is provided with a runner 4:. Supports 5 connect the body to the pontoons and these supports may advantageously take the form of tubular members having flanged ends which may be bolted, riveted or welded to the body and the pontoons. Angularly disposed braces 6 may beused to make the connection between the body and the pontoons more rigid.

The guiding mechanism takes the form of rudders 10, one of which is connected to the rear of each pontoon by a universal joint 11. As shown in Fig. 3 the two rudders are tied together by a cross rod 12. A steering wheel 13reciprocates a rod .14 longitudinally and the end of this rod is connected to. a bell bracket 17 so that it can pivot in a vertical plane. it will be seen that by reciprocating the rod 14 the bell crank 15 is pivoted to cause lateral movement of the tie rod 12 which inturn moves the rudders 10.

When the device is on ice the lower edge of the rudders engage with the surface of the ice and they may be turned from side to side to guide the boat. WVhen the boat is in water it is desirable to have the rudders 10 extend further downward so as to lie within the water. Due to the fact that the rudders are mounted on the universal joint 11 and the bell-crank can pivot in a vertical plane on the bracket 17, the rudders will have a ten the boat is in water. The position of the rudders, when the boat is in water, is shown in dotted lines of Fig. 1.

This rudder arrangement is advantageous should the boat, when in use, suddenly come to the edge of the ice and drop off into the water. ately accommodates itself to guide the boat in water.

I am aware of the fact that various combined boats, such as ice and land boats, have been heretofore proposed, but inso far as I am aware these boats require considerable change in order to adapt them for their different uses. According to my invention no clnnge is required and the steering mechanism automatically adjusts itself to either ice or-water. steering mechanism shown, nicely accom plishes the guiding in both uses, but the structure might be changed in various details and it is intended that such changes be within the sco ie of this invention.

2. In a combined iceand water-boat, a steering mechanism comprising a rudder, a universal joint connection between the rudder and the boat, means independent of said universal connection for pivoting the rudder laterally for guiding purposes, said universal connection permitting the rudder to adjust itself for guiding the boat on ice or water and means acting on the rudder to of feet an automatic adjustment thereof.
